Auxiliary rubber spring for automobile suspension
First Claim
1. An auxiliary rubber spring for an automobile suspension, comprising:
- N layers of metal partitions, N being an integer greater than or equal to 1, and a transverse section of each metal partition having an arc shape;
N+1 rubber layers, the rubber layers being alternately lapped with the metal partitions, and a transversal section of each rubber layer having an arc shape;
a supporting plate provided with a first convex arc surface on one side thereof, the first convex arc surface being bonded to a first concave arc surface of an outermost rubber layer; and
a connecting plate provided with a second concave arc surface on one side thereof, the second concave arc surface being bonded to a second convex arc surface of another outermost rubber layer,wherein the rubber layers and the metal partitions are provided with a through hole or a blind hole therein extending in a thickness direction of the auxiliary rubber spring, the thickness direction extending between the supporting plate and the connecting plate, andwherein a top surface and a bottom surface of each metal partition is encapsulated by two adjacent rubber layers, and end surfaces of each metal partition are covered by an encapsulating layer.
